NAME
	timeprefix - Prefix the current time to each line

SYNOPSIS
	timeprefix

DESCRIPTION
	timeprefix reads stdin line by line and prefixes the current
	time (at the point the line has been fully read) to each line
	and prints the prefixed line to stdout.

	The timestamp is written in both decimal boot time and
	human-readable real time (in UTC), with the boot time first so
	that multiple generated log files can be merged into one with
	sort -m.

	timeprefix also marks when the program started and terminated.
